<title>Abstract</title>
We investigated the long-term effects of birthplace favoritism by top-ranking politicians on the quality of education in Vietnam. We used over 1 million test scores from the 2009 and 2014 Vietnamese national university entrance examinations. We examined both the different timing of political terms and the total years of birthplace favoritism. Using the school fixed effects, we found that birthplace favoritism did not have any significant impacts, regardless of the timing and duration of such favoritism. We did not find evidence for such impacts in the distribution of test scores either. The results also suggest that national entrance examinations were unaffected by birthplace favoritism up to 2014.

<title>Abstract</title>
In literature, there is limited direct evidence regarding the effect of health insurance coverage on firm performance and worker productivity. We study the impacts of health insurance on medium- and large-scale domestic private firms’ performance and productivity in Vietnam, using a large firm level census dataset. We find statistically, but suggestive, positive health insurance effects on both aggregate profit and profit per worker for both complying and non-complying firms when using the full sample. We further restrict the sample to specific industries. The positive health insurance effects could exist for both complying and non-complying firms in the heavy manufacturing and construction sector, while such positive effects could be only significant for complying firms in the wholesale/retail sectors. We could not find any evidence of positive health insurance effects in the light manufacturing sector. These results imply that the impacts of health insurance could be industry specific.

This study examined the survival of multinational enterprises (MNE) in Vietnam during 2000-2011 using Cox hazard models. The characteristics and ownership structure of firms and the nationality of foreign partners are found to be associated with the probability of firm exit, with a firm having greater capital share of foreign partners surviving longer. An efficient local government requiring less time for bureaucratic procedures and inspections is found to be associated with a lower probability of MNE exiting. Meanwhile, transparency in business regulations and predictability in implementing central government policies accelerate the survival of highly competitive MNE.

Using information on 1045 pairs of Japanese monozygotic twins, we examined differences in education by considering both the years of schooling (quantity) and the reputation of the last attended school (quality). We found that a difference in learning performance at 15years of age is one of the key factors determining the differences. We also found that a female eldest child in the family from the 1950s and 1960s birth cohorts averaged 0.54years less schooling than did her younger' twin. However, for the same birth cohorts, a male eldest child in the family generally had access to higher-quality education than his younger' twin. Nonetheless, as the Japanese economy matured in the 1970s and thereafter, educational differences between twins disappeared, regardless of gender and sibling order.

This paper examines sex preferences for children in Vietnam using the mother birth cohort from 1972 to 1993. We specify the full set for sex-birth order composition of existing children using a split-population model. The model relaxes the assumption in conventional hazard models that all mothers would eventually have another child. Our results indicate a preference in these families for one male offspring. In addition, we observe a mixed sex preference at the fourth birth order. We also establish that a one-square-meter increase in household living area, as a proxy for the increment in household wealth, is associated with a 0.997 times lower preference for a son for the second childbirth, but a 1.015 and 1.014 times higher preference for a son for the third and fourth childbirths, respectively. As long as two-child families dominate the population structure, these results suggest that the importance placed on economic reasons for a son preference will gradually weaken as economic development proceeds in Vietnam.

We examine the gender gap in housework in Vietnam among siblings aged less than 18 years. We show daughters undertake 5.25 minutes more unpaid housework per day than sons. However, the gender gap in housework is negligible for children aged less than 14 years. A decline in the gender gap at 15 years of age suggests parents eventually begin to consider the education of their daughters. Before then, however, the gender gap increases with age and can be even greater if daughters also engage in paid work.
